Archimedes arches are widely used in shaping the surface of cutting tools, particularly cutting tools for machining Gleason spiral bevel gears. Relieving surfaces are often machined by specialized machines, but now digital-controlled tools are also used to machine Archimedes relieving surface. However, there is a lack of database for selecting the appropriate set of technological process parameters for machining on CNC machine, thus current actual manufacturing requirements cannot be met. The paper presents the simultaneous effect of process parameters (V, S, t) on surface roughness (Ra) when machining Archimedes surface of end mill tooth of Gleason spiral bevel gears by ball nose end mill on the Super MC CNC machine. Research findings are the basis for technologists to select an Archimedes arch machining method and appropriate process parameters to increase surface quality, precision and productivity in Archimedes surface machining on the Super MC CNC machine.

Keywords: Process parameters, roughness, Archimedes, CNC machine, relieving.
